Human Resources


REN's human capital management is aimed at ensuring the necessary skills for complying with its mission and the development and enhancement of people.

REN also invests in the preservation of an environment of labour stability based on dialogue with employees. Due to the role that REN plays in the energy sector, particularly in terms of competence in fulfilling its mission and the quality of the public utility services that it provides, it continues to be highly attractive in the labour market.

REN includes in its activities various aspects relating to safety include the implementation of measures conducive to the prevention of potential foreseeable accidents, minimising inherent risks and mitigating the consequences of those that result from them, by applying the best safety practices in force in the energy transmission sector.

These best practices include:

- Audits, checks and monitoring of working conditions;

- Production of key internal documents to ensure compliance with safety requirements;

- Training courses at work sites for specific activities, as well as additional training in such activities as first aid, basic life support and fire prevention;

- Provision of individual protection equipment suitable for each activity;

- Inspection and coordination of safety at work that cumulatively ensures proper use of individual and collective protection equipment;

- Organisation of drills and exercises.

REN invests in the training of all employees (including subcontracted workers) involved in the construction of lines, substations, gas pipelines, stations and other energy transmission system facilities that may put workers at risk, with a view to minimising the occurrence of accidents. In the case of the conservation of the RNT and RNTIAT infrastructures, all service providers undergo prior safety-related  awareness courses.

Emergency Responses

Emergency responses are a discipline that combines specific procedures to minimise the effects of an emergency caused by an incident.
Intervention is timed to occur immediately after the occurrence and detection of the emergency.

As it is impossible to eliminate risks and guarantee the absence of incidents, the aim of these procedures is to reduce their impact and speed up the recovery process.
Impact reduction is backed up by preventive action based on analyses and results of drills and exercises and analysis of specific scenarios.

Analysis or assessment of means and measures to be provided can be based on the World Economic Forum – Global Risk, 7th edition, which classifies global risks into five categories – economic, environmental, geopolitical, social and technological. This makes it possible from the global concept and global responses, to interrelate risks and impact versus the importance of the assets under threat and, therefore, to what extent they should be protected. 
From any perspective, as mentioned, decisions must always be based on information gathered in the analysis of results in drills and scenarios undertaken for the purpose and in the history of similar or equivalent occurrences.
Considering the utopia of a risk-free society, global security is unconceivable and we have to carefully take account of the fact that the economic crisis has heightened the problem of crimes against property.
Indeed, this new factor has been reflected in incidents affecting energy transport systems. They are certainly more worrying than those of a technological nature, due not only to their frequency but also to the way in which they can affect continuity of operations.

This means that scenarios, drills and exercises have to be rethought and, without setting aside industrial incidents that are currently the main focus, we must add factors and influences possibly resulting from acts of vandalism, sabotage or even terrorism, which may be given specialised handling. 
These are factors that require close attention due to their effects on the operation of systems and their possible effect, over time, on the continuity of energy transport and service and an increase in interruption times.

Safety of infrastructures

Natural Gas Perspective

The safety of the REN group natural gas infrastructure is ensured through active procedures and measures which seek to minimize the probability of incident occurrence, bringing it down to acceptable levels. Moreover, passive procedures and measures allow the impact of any actual incident to be reduced. Compliance with technical standards and national and Community legislation is a minimum requirement. It should also be noted that REN exceeds this requirement by permanently applying the best international practices in line with sector developments.

Examples of active procedures and/or devices include:

• In the case of the high-pressure NG transmission network, the implementation of restrictions of use in the field within the entire easement route and in-line inspections by smart tools as part of the management programme on infrastructure integrity.

• With regard to the Carriço underground storage, the adoption of the minimum safety distance between the outside walls of the different cavities and monitoring of soil subsidence.

• At the Sines LNG terminal, the safety control system, which is independent of other monitoring and process control systems, automatic start up of facility protection actions after certain pre-established events take place and the permanent availability of a technician responsible for the facility who is capable of dealing with unforeseen operating conditions.

Examples of passive procedures and/or measures include

• In the case of the high-pressure NG transmission network, the isolation valves in the main gas pipeline which can be activated from the Dispatch Centre and allow sections of pipeline to be isolated if required and the triggering of safety and emergency plans in the event of an incident;

• With regard to the Carriço underground storage, the activation of the below surface safety valves (SSSV) in pipes connecting the tops of the cavities to the surface and the triggering of safety and emergency plans in the event of an incident;

• At the Sines LNG terminal, the existence of retention bays to contain LNG spillages;

• At both the Carriço underground storage facility and the Sines LNG terminal, triggering of the Safety Management and Serious Accident Prevention System (Decree Law No 254/2007 of 12 July 2007).


In addition to compliance with legal and regulation requirements, more demanding complementary measures have been implemented. Of note are the drawing up of risk analyses and risk mitigation procedures as well as monitoring of activities where moderate to high risk is involved.

Electricity Perspective

One of the most distinctive features of the National Transmission Network infrastructure is its extensive geographical coverage. This feature makes it naturally more susceptible to weather and environmental phenomena and break ins.

With regard to very high voltage overhead lines, it is weather and environmental factors which have greatest impact. It should be noted that more than 80% of network incidents originate in lines and the 4 most frequent causes are atmospheric discharges, forest fires, pollution related haze and birds. 

Impacts on sub-stations are more localized and in principle, easier to control.

Incidents result either from equipment failures which jeopardize people and facilities or (with greater impact on safety) as a result of break ins.

Of particular concern are intruders seeking to steal valuable metals (copper, iron, aluminium, etc.). This type of vandalism is also taking place outside sub-stations and recent months have seen a growing number of thefts of iron parts used for line support.

Infrastructure surveillance for the integrity and continuity of service, including repair in the event of incident, is carried out in the System Manager Control Rooms and particularly by the Network Operation Department which uses SCADA and other tools to supervise facilities. These tools provide remote access to chronological records as well as facility status and alarms. When necessary, intervention by service teams from the Operations Department is requested.

With regard to attempted facility break in, REN has installed video surveillance systems which are complemented by intruder detection systems. These systems, which are centrally operated and supervised from the Surveillance and Service Centre in Vermoim, allow early detection of intrusion attempts. Authorities are immediately alerted to ensure fast and efficient intervention.

These systems have a dissuasive effect which we believe has helped reduce the number of break ins and thefts from facilities.
